Abstract

The paper deals with the evaluation of field concrete strength placed on construction sites in Dakahilia, Egypt in the years 1994 – 2000. The main purpose of this research was to study the variability of concrete strength produced in different location on sites. Using the information of cube compressive strength data, probabilistic models have been developed to describe the variability of concrete compressive strength between locations. A total 859 concrete samples were randomly collected from construction sites for strength testing at strength of material laboratory, Mansoura University. The result indicate that concrete is well modeled by the normal distributions. Also, the results of the analysis showed the coefficient of variation are higher for this study than normal, The mean-to-nominal strength ratio varies between 0.99 and 1.05, whereas the coefficient of variation is in the range of 27.47% 35.81%, depending on the location of concrete. The models are verified by ꭕ2 and Kolmogorov - Smirnov goodness of fit tests at the 5% significance level. The models developed in this paper are useful for predicting the performance of structural element and assessing their reliability levels.
